What is the principle of capillary air conditioning? What is refrigerant and what is its composition?

The refrigerant is water, and the component is PPR plastic capillary.

Principle: Capillary radiation air conditioning system adopts 3.35X0.5 mm PPR plastic capillary with a spacing of 10 mm _ 30 mm, just like the capillary in human body, which plays the role of distributing, transporting and collecting liquid. The liquid velocity in the grid is basically the same as that in the human capillary, both of which are between 0.05 _ 0.2 m/s. At the same time, the capillary of human subcutaneous tissue successfully exchanges heat with the surrounding environment to achieve the purpose of self-temperature regulation.

Extended data

Capillary radiation system regulates the temperature through the circulation of "water" in capillary grid. The capillary grid is made of PP-R or PE-RT plastic, which is hot-melted, recyclable and environmentally friendly. Capillary grid is a water collecting structure, which is formed by connecting a plurality of thin tubes in parallel, and has a large circulation area and is not easy to be blocked; The heat exchange area is large, so the heat transfer efficiency is high.

Capillary radiation system regulates indoor temperature through "water" circulation instead of "wind" convection, which is comfortable; Cooling with high-temperature cold water in summer and heating with hot water in winter, the water temperature is closer to the indoor temperature and softer; Radiate heat transfer with the whole board surface, with uniform heat dissipation and stable temperature field. Therefore, capillary air conditioning is more comfortable than traditional air conditioning.
